To all whom it may concern; I

Be it known that I, THOMAS F. STUBBLE- FIELD, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Revolving Advertising Devices; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same. 1 1

The invention relates to improvements in revolving advertising devices;

The object of the present invention is toimprove the construction of revolving ad vertising devices and to provide, a simple, practical and comparatively inexpensive advertising device designed for use in show windows and various other places and equipped with advertising cards adapted through the rotary movementof the device to reverse themselves automatically so as to display both sides of the card at intervals.

A further object of the device is to pro vide a rotary advertising device of this character adapted to be read from either side, that is to say, from the front or backofthe advertising device and equipped'with clock mechanism and adapted to catch the eye and hold the attentionwhile the advertising wheel is making a complete revolution or until it hasdisplayed its entire advertising matter. 7

It is also an object of the invention to provide a rotaryadvertising device of this character adapted to afford a maximum advertising space and adapted to permit the cards to be removed and replaced without stopping the device.

'With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying'drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Like numerals responding parts drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the rotary advertising device comprises in its construction, a main drive wheel 1 mounted on a hollow shaft 2 and havlng internal gear teeth and connect ed by a train of gears with an inner horizontal shaft or axis 4 arranged within the hollow-shaft 2. The hollow shaft carries the hour hand 6 and the inner shaft 4 carries the minute hand 5. The teeth of the train of gears being proportioned to cause the hour hand to travel one-twelfth as fast as the minute hand. The hollow shaft is journaled in suitable bearings of a frame composed of front disk or plate 7 and a rear disk or plate 8 connected with the front plate by bars 9 which have terminal attaching portions 10 for securing the main or supporting frame to a suitable support. The disks or plates 7 and 8 are preferably open as shown but any other suitable supporting frame may of course be employed. The train of gears for connecting the main drive wheel with the inner minute hand shaft consists of inner, outer and intermediate gears 11, 12 and 13' meshing with each other as clearly illustrated in Fig. 4: 0f the drawings, the inner gear 11 being mounted on the shaft 4 and the outer and intermediate gears 12 and view on the of reference designate corin the several figures of the 13 being arranged on shafts or arbors 14 and 15 supported by the rear disk or plate 8 of the main or supporting'frame and }a plate 16 arranged within the main or supporting frame and suitably secured to the snared plate with its body por-tion in spaced relation with the same. I

The main drive wheel which may be spring actuatedis illustrated in the drawings as actuated by a" weight 17 connected'to one end of a cord 18 which has its other end connected with andadapted to be wound on -a cylinderor drum .19 mounted on the shaft 2 and provided with front and rear rims, the rear rim being provided with ratchet teeth 20, which are adapted to beengaged by aspringactuated pawl ordog 21 that is carried by the main d'r-iv'e wheel. This provides a ratchet or clutch connection between the drum and the main drive 'yvlieel to enable the drum to :be rotated independently of the main or drive wheel for winding up'the lweight'tor spring. 'The front rini'iof I the drum is provided withbevel gear teeth 22 which meshes with a bevel pinion 2336f a winding shaft 24 journaled' in 'silitable bear:- ings of, the front disk onplat'e 7 of the main orsupporting frame and provided at'itsout er end with a suitable handle or grip 25'. The winding shaft 24: is'adapted to be rotated to turn the drumflor cylinder on the shaft 2 for winding up the Weight but any 7 other suitable means'may'of coursebie employed for effecting this operation of rewinding the clock mechanism. The winding shaft extends beyondthe periphery of the supporting frame and is adapted to be *readily grasped to rotate the drum or cylinder 1 which is interposed between the main drive wheelv and the-front disk .or plate 7.

Mounted upon the main hollow shaft 2 which carries the hour hand 6 is an escape wheel '26 which is provided with a substantially annular 'slo't'o'r opening 27' composed of straight' angularly related portions forming inner and outer scalloped edges 28.. and 29 which are adapted to engage a 'detent' 30 of a pendulum 31 pivotally mounted at 32 on a suitablepin or pivot and preferably of a length to oscillate'during'the periodof. a second and the angularly disposed portions and scalloped edges are of sufficient-number to'cause the escape wheel to make one complete revolution" during the period of a minute.

"The escape wheel imparts periodic impulses to the pendulum which alternately engages the inner and outer edges of the angularly related slots of'the escape. wheel. The

detent 30 of the pendulum is approximately L shaped and consistsof an arm"having a laterally projecting terminal" portion 33 which extends between the inner and outer scallops or angularly related'edges of the escape'wheeL' w q The escape wheel which is loosely mounted on the hour hand shaft 2 is connected with the inneror .minute hand shaft A by a train of gearscons'istingof a pinion'3 1mounted on thehub 35 of the escape wheel and meshing with a gear-wheel 36 fixed to a shaft or arbor 37 which journaled in suitable bearingsof the front-and rear disks or plates of the" main or supporting frame. The shaft arbor '37 has keyed or otherwise secui' ed to its rear end a pinion 38 which meshes with a gear wheel'39 mounted on the rear end of the shaft &. The train of gears is properlyproportioned so that the minute hand shaft will travel at the proper rate of speed,' with relation-to the rotation of the escape wheel.

-aThe escape wheel is connected with a 1'0- tar-y advertising wheel or frame 40 preferably consisting of spokes 41, and inner and outer-concentric rims l2 and i3 suitably cured to the spokes whi h ar a ed to the escape wheel. The advertising wheel which may be of any other desired form has inwardly-tapered openings 44 in which are pivoted holders 4:5'60mpQsed of inner and outer arms 16 and 417 having radially alined pivots 48 and 9. hich are mounted in suitable bearing'openipgs in th inn r and outer I'HIIS.

The pivots are disposed centrally of the inner and'outer ends of the tapered faces and the arms terminate short of one side of t e facesiso" thatjth tra ers cqnne t ng portions 45 and the arms constitute a'gravy a ting holder w e h s ov s 9 .1 the reception'ofcards 51 bnt'plates or any other suitab e means may of course be employed to fo pi ta g avity act ng members orsection will be displayed dur ng a portion of the rotation of the ad erti ing whe Also the free pivotal movement of the holders will ena le h ntents ther of to be'readily changed without, stopping the advertising devicei The advertising device is provided with a dia1' 2 whi h may m nt ined s ationy in any s i able mann r The dial .52 is supported by upper and lower rac s sec d to he support on which the advertising device is mounted and extending therefrom to the dial at the top and bottom thereof as clearly shown in Fig. These braces by being arranged at the top and bottom of the advertising device may be conveniently employed for concealing the pivoted cards and their holders while the same are being reversed.
